Power pass sequentially through the second transmission axle 6, planet carrier 321 and gear ring 322 and pass to the first input shaft 21, meanwhile, described first
Motor 33 and the second motor 41 are provided which that power, the power of the first motor 33 pass sequentially through the first transmission axle 5, sun gear
323 and gear ring 322 power of first motor 33 passed into the first input shaft 21, the power of second motor 41 passes to
Two input shafts 22, meanwhile, the first axle gearshift 241 on first input shaft 21 is placed in left gear or right gear, will send out
The hybrid power of motivation 31 and first motor 33 passes to output left gear 261, and the second axis on second input shaft 22 changes
Blocking means 251 are placed in left gear or right gear, pass the power on the second motor 41 to output left gear 261, then, the hair
The power of motivation 31, first motor 33 and the second motor 41 realizes final mixing, the left tooth of output at output left gear 261
Wheel 261 drives vehicle driving, realizes large torque by the way that final mixed power is passed to wheel after engaging with differential mechanism 27
Driving.
Four, Brake energy recovery
When driver touches on the brake, first motor 33 and the second motor 41 can absorb power and charge a battery, and produce
Raw brake force.
Five, the continuous shift speed change function of power failure-free
During above-mentioned pure electric vehicle driving, combination drive and Brake energy recovery, from first motor 33
Power passes to shift speed change module 2 by the first transmission axle 5, and the power from engine 31 is transmitted by the first input shaft 21
To shift speed change module 2, the power from the second motor 41 passes to shift speed change module 2 by the second input shaft 22, or
Brake force is passed to from shift speed change module 2 by first motor 33 and the by the first transmission axle 5 and the second input shaft 22 respectively
Two motors 41.In above-mentioned transmittance process, if 33 electric current of first motor is zero, the torque of first transmission axle 5 is zero,
And then the torque of first input shaft 21 is zero, the first axle gearshift 241 can replace another gear, shift
After the completion, the power of the power reply power supply of the first motor 33, first motor 33 and engine 31 passes through shift speed change mould
Pass through the gear driving driving vehicle driving after shift, during first axle gearshift 241 is shifted gears, described the after block 2
Two motors 41 still keep power, drive vehicle driving by some gear in shift speed change module 3, keep entire shift process dynamic
Power will not interrupt；If the electric current of the second motor 41 is zero, the torque of second input shaft 22 is zero, relative second
Axis gearshift 251 can replace another gear, after the completion of shift, 41 power reply of the second motor power supply, and second
41 power of motor drives vehicle driving by the gear after shift, during the second axis gearshift 251 shift, institute
It states engine 31 and first motor 33 still keeps power, vehicle driving is driven by some gear of shift speed change module 3.On
It states in shift process, entire shift process power does not interrupt, realizes variable speed of the power without interruption.
Preferably, first axle gearshift 241 and the second axis gearshift 251 described above is gear teeth set
Attachment device.
The first axle gearshift 241 and the second axis gearshift 251 be it is any by the engagement of two elements or point
From device.
Embodiment two:
In the present embodiment, referring to Fig.2, what is different from the first embodiment is that the first motor 33 passes through the first transmission axle 5
It is connect with the hybrid power module 3 and the first motor 33 in embodiment one is replaced directly to connect with hybrid power module 3.And
After increasing by the first transmission axle 5, set cylindric for first input shaft 21, first input shaft 21 is set in described
The outside of first transmission axle 5, connection relationship does not change between other parts, the function and embodiment which realizes
The function of realizing in one is identical.
Embodiment three:
In the present embodiment, refering to Fig. 3, unlike embodiment two, only by the shift speed change module 2 in the present embodiment
With the location swap of hybrid power module 3, it is, first input shaft 21 is set in the outer of second transmission axle 6
Connection relationship does not change between the other parts in face, the function phase realized in the function and embodiment two which realizes
Together.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
